TEXTILE SPINDLE Filed Jan. 2, 1947 INVENTOR I ATTORNEYS Patented Aug. 7,i951 UNITED STATES ATENT OFFl CE 1 I 1 2,563,398 I I j TEXTILE SPINDLE 2Claims. 1

This invention relates to textile spindles utilized in the manufactureof yarns.

Such spindles have been so constructed that when the parts have wornsubstantially, particularly the driving lugs which nest in the bottom ofthe spool or bobbin, the entire spindle must be discarded and replacedwith a new one, which constitutes a substantial item in the cost ofupkeep. This wear is due to the fact that each spindle has a wharve, i.e., a flywheel, in consequence of which the spindle is frequently rotating at substantial velocity when a bobbin is doffed and a fresh bobbinemplaced. Due to the consequent relative motion as between the bobbinand the spindle, at the time of dofling and replacement, the drivinglugs wear and eventually the driving connection is so impaired as torequire replacement of the entire spindle.

The primary object of my invention is to provide an improvedconstruction of spindle whereby when the driving lugs wear, they can bereplaced, the remainder of the spindle being preserved.

More specifically, it is an object of my invention to provide an adapterwhereby a worn spindle can be repaired and again put to use.

How the foregoing, together with such other objects as may hereinafterappear or are incident to the invention, are realized is illustrated inthe accompanying drawings, wherein Fig. l is a partial side elevation insection through my improved spindle, showing the bobbin in place.

Fig. 2 is an enlarged section taken on the line 2-2 of Fig. 1.

Fig. 3 is a plan view of the top of the wharve of the spindle, drawn onan enlarged scale.

Fig. 4 is a perspective of the adapter of my invention, and

Fig. 5 is a sectional view illustrating a modification of the adapter.

Referring now to Fig. 1, the reference numeral 1 indicates the wharve orflywheel of the spindle; and the reference numeral 8 indicates thespindle or shaft proper which, as in conventional practice, is pressfitted or otherwise secured to the wharve so as to constitute, for allpractical purposes, a unitary structure. As is customary, the lowerportion of the shaft or spindle 3 projects below the wharve so as to bereceived in the bearing 9 supported in any preferred manner in the frame[0. The upper portion of the spindle projects above the wharve toreceive the bobbin or spool I I. The wharve is provided with a pulleyportion 1' to receive the customary driving belt (not shown) 5 Edward J.Courtney, Oaklyn, N. J. Application January 2, 1947, Serial No. 719,817,

The reference numeral l2 indicates the driving lugs on the upper end ofthe wharve "I. In this instance, however, such lugs, instead of beingformed integrally with the wharve, are carried by the disk or plate [3which is preferably a stamping for reasons which will appearhereinafter. The lugs l2 may be made of especially hard steel and weldedor otherwise unitarily se cured to the plate [3, as shown in Fig. 4; ormay be stamped as part of the plate I3 as shown in Fig. 5, so as toconstitute an integral part of the plate I3.

The plate l3 fits on the top face of the wharve l and is secured theretoby means of taper head screws [4, for which purpose the plate I3 isprovided with countersunk screw receiving holes IS. The wharve has, ofcourse, tapped holes I l to receive the screws. The plate has a centralopening it to receive the spindle and the driving lugs are located onopposite sides thereof.

By stamping the screw receiving holes l5 in the plate 13, a rim or burrl5, best shown in Figs. 2, 4 and 5, is formed of the metal immediatelyadjacent the holes, such burrs projecting downwardly somewhat below thelower face of the plate. The upper portions of the screw-receiving holesI! in the wharves 1 are also tapered at a somewhat flatter angle thanthat of the screw heads, in consequence of which the burrs or rims l5fit down into the screw holes ll, when the screws 14 are tightened home.Thus, the screws are relieved of part of the driving thrust and a firmconnection is obtained between plate and wharve. Of course, the rims orburrs can be otherwise formed, but by employing a stamped plate, theconstruction is quite cheap and metal which would otherwise ordinarilybe scrapped can be employed.

When the driving lugs wear, it is obvious that a new plate with itsdriving lugs, can be substituted, and the worn one discarded. Thereplacement can be made at very low cost as compared with discarding thespindle, as has been universal practice.

Similarly, it will be seen that a worn spindle of conventionalconstruction can be readily repaired by cutting off the existing lugs,drilling and tapping screw receiving holes in the top of the wharve, andapplying the adapter of my invention. Even this operation is a verycheap one as contrasted to providing an entirely new spindle.

I claim:

1. In a textile spindle, a wharve provided with spaced threaded recessesin its top portion, a replaceable disc having correspondingly locatedholes therethrough and adapted to seat on the top of the wharve, saiddisc having spaced bobbin driving lugs on its upper face, and screwsthreaded into said recesses in the top portion of the wharve and fixedlysecuring said disc to said 5 wharve.

2. In a textile spindle, a wharve provided with spaced threaded recessesin its top portion, a disc having correspondingly located holestherethrough and adaptedto seat on the top of the wharve, said dischaving spaced bobbin driving lugs on its upper face, and screws forsecuring said disc to said wharve, said recesses and said holes beingcountersunk to receive taper head screws, and said disc having annularrims surrounding said holes on the face of the disc next to the wharve.
